Damn this is interesting. I prefer Gutenburg because it seems way more intuitive to me. I love all the blocks and I don’t see how it slows anyone down but maybe thats just me. I usually copy paste my stuff from google docs into gutenburg and it saves all my headings and stuff so its a god send.
I was hating on the Gutenberg for a LONG time. Still doesn't make sense to me, but I've got used to using it. Figured, if that's the way WordPress wants to go I might as well get myself familiarized with it.
If there's a blog post I'm formatting a particular way I'll still use the Classic Editor..
